Early development of Grateloupia turuturu (Halymeniaceae, Rhodophyta)

Grateloupia turuturu is a commercial red alga with potential value in nutraceuticals and pharmaceuticals. To supplement information on its life history and verify whether carpospores can be used for seedling culture, early development of G. turuturu was investigated under culture conditions （27~C, 10-13 ~mol/（mZ.s） in irradiance, photoperiod 10：14 h L：D）. Three physiological stages were recognized by continuous microscopic observation： division stage, discoid crust stage, and juvenile seedling stage. At the beginning of the division stage, the carpospores developed germ tubes into which the carpospore protoplasm was evacuated, and then the carpospore protoplasm in the germ tubes began to divide continuously until discoid crusts formed. Finally, upright thalli appeared on the discoid crusts and developed into juvenile seedlings. It took about 60 days for carpospores to develop into juvenile seedlings. The growth parameters, including germination rate for carpospores and discoid crust diameter, were recorded. These results contribute more information on the life cycle, and at the same time are of great significance in the scaling-up of artificial seedling cultures of G. turuturu.

Research on Development Trend of Automobile Electronic Technology

Along with the popularization of artificial intelligence and information technology, the development of automobile industry have been closely combined with information technology, environmental protection and energy saving ideas, promotion and application of electronic control technology, which development cycle becoming shorter and shorter. In this paper, through the analysis of the present application situation and development trend of the automobile electronic technology at present, in order to provide a theoretical reference for the future development of the automobile electronic control technology.

Image Segmentation Based on Period Difference of the Oscillation

A new method for image segmentation based on pulse neural network is proposed. Every neuron in the network represents one pixel in the image and the network is locally connected. Each group of the neurons that correspond to each object synchronizes while different groups of the neurons oscillate at different period. Applying this period difference, different objects are divided. In addition to simulation, an analysis of the mechanism of the method is presented in this paper.

Acupuncture and moxibustion for functional hypothalamic amenorrhea by establishing artificial cycle:a controlled trial

Objective To observe the clinical efficacy of acupuncture and moxibustion in treatment of functional amenorrhea by establishing artificial cycle.Method One hundred and twelve eligible patients with functional amenorrhea were divided into an acupuncture-moxibustion group（64 cases） and a western medication group（48 cases） by adopting random method.According to the pattern differentiation of amenorrhea of traditional Chinese medicine,the patients in the acupuncture-moxibustion group were classified into two types：amenorrhea due to blood depletion and amenorrhea due to stagnation of blood.For patients with amenorrhea due to blood depletion,Guanyuan（关元 CV4）,Zhongji（中极CV 3）,GuiTlai（归来ST 29）,Geshu（膈俞 BL 17）,Ganshu（肝俞BL 18）,Pishu（脾俞 BL 20） and Shenshu（肾俞 BL 23） were selected.At first,BL 17,BL 18,BL 20 and BL 23 were needled;after deqi,reinforcing method was applied,and the needles were not retained.Then,warmingneedle moxibustion was applied at CV 4,CV 3 and ST 29,and the needles were retained for 30 min.For patients with amenorrhea due to stagnation of blood,CV 3,Qihai（气海CV 6）,Xuehai（血海 SP 10）,Sanyinjiao（三阴交 SP 6）and Xingjian（行间 LR 2） were selected,reducing method was applied,and the needles were retained for 30 min.The treatment was performed once a day,and treatment for 15 consecutive days were the 1st cycle.The 2nd and3 rd cycles started from the 5th day of menstruation（for the patients still not menstruating,the 2nd and 3rd cycles started from the 29 th and 57 th days since the 1st day of treatment）,and the treatment lasted for 15 days.Three cycles were needed.In the western medicine group,estrogen-progestogen was taken orally for 21 days（one cycle） to establish a artificial cycle.The levels of FSH and LH were tested and compared on the 3rd day of menstruation before treatment and after the 3rd cycle of treatment,and the adverse effects were analyzed statistically.Follow-up visit was conducted for the patients after treatment for three cycles,and the recurrence rate was calculated.Result The levels of FSH and LH of patients with functional amenorrhea were enhanced significantly through establishing artificial cycle by acupuncture and moxibustion.There was no significant difference between the acupuncture-moxibustion group and the western medication group in effective rate（P〉0.05）;but the adverse effect rate（1.49%） and recurrence rate（25.0%） of the acupuncture-moxibustion group were lower than that of the western medication group（with the adverse effect rate of 4.14%,and recurrence rate of 69.8%）（both P〈0.05）.Conclusion The levels of FSH and LH of patients with functional amenorrhea can be enhanced significantly through establishing artificial cycle by acupuncture and moxibustion.The efficacy of acupuncture and moxibustion in treatment of functional amenorrhea by establishing artificial cycle is equivalent to that of oral administration of estrogen-progestogen in treatment of functional amenorrhea by establishing artificial cycle,but the adverse effect rate and recurrence rate of acupuncture and moxibustion group are lower.
